Chronographs by Longines are considered to be amongst the best and most attractive in the world and have been celebrated for the accuracy and quality, starting with caliber 13ZN in the mid 30’s the brand developed a new manually wind caliber 30CH a decade later. Designed in 1963 at a time medical diagnosis would essentially depend on the precision of the instruments used by the doctor, the present reference 6592 is powered by this famous flyback caliber 30CH. As a tool watch designed for doctors, the dial of this watch displays two important scales. In red, a scale that allows easy calculation of the heart beat based on 30 pulsations and in blue another one to identify the number of respirations per minute.

The overall layout of the dial has also been designed to ease the legibility of the chronograph function by having the dial and the minutes and hours hands of light colors that contrast with the dark blue of the chronograph hand. This rare example, preserved in excellent condition with its refined and contemporary design, is a quintessential mid-century chronograph. But don't worry, you don't need to be a doctor to appreciate this beauty.
